I’ve been interested in slide rules for a long time, going back to when I got my very first slide rule in Grade 12 (1986-87) from one of my math teachers. It was a pretty basic student level slide rule, but I taught myself how to use most of it and used it for a few years during the rest of high school and for the first few years of university.
I wouldn’t consider myself a collector, but I’ve managed to acquire a few different slide rules over the years.
